9 Claims. (Cl. 130-5) This invention relates to corn husking mechgles with a plane perpendicular to the axis of anisms of the type comprising a plurality of the roll, the strength of the peg to resist the husking rolls equipped with husking pegs, and stresses imposed upon it is greatly increased the object thereof is to provide a new husking over that of prior pegs, and by flattening the 5 peg and means for securing it in position in a end of the peg into a plane perpendicular to the 5 husking roll. leading edge, a relatively sharp point is provided It is a common practice to provide in husking at the outer end of the edge, which gives the peg rolls husking pegs in the form of relatively flat exceptionally good husking characteristics. projections, such as disclosed in Patent 1,970,797, A preferred embodiment of my invention is de- 10 issued to me on August 21, 1934, or in the form scribed in the following specification and dis- 10 of pins of circular cross-section, and to fix these closed in. the accompanying drawing in which: in position in the husking roll by inserting wood- Fig. 1 is a fragmentary top view of the deliven plugs in radially extending holes in the huskery end of two rolls of a corn husking mechaing roll, and then driving the pegs into the plugs. nism, one of which is equipped with my new Driving a peg of either of these shapes into a husking pegs; 15 wooden plug splits the plug into two parts, caus- Fig. 2 is an enlarged top view of one of the ing the two parts of the plug to act as wedges to pegs mounted in position; hold the peg in position.

It is angular in cross-section, comis driven into a wooden plug, too much of the prising tWO flanges and is, disposed a a stock of the plug is ruptured to obtain a good angle of 0 degrees to each other.

As a result, a sharp point [9 the required strength will be obtained without is formed at the junc u of this e e W h h 40 resorting to heavy stock material, and such that d of the peg.

To accomplish this, I provide a peg y inserting a Wooden p 25 in a radially exwhich is angular in cross-section, the material tending hole 26 in the Wall 21 0f the husking itself being relatively thin. The angular cross- T011, d e driving the g into the o section causes the wooden peg to be split into p until Sh u de s 2i and 2 Contact the end 50 three parts.

The peg i positioned W h e edge at the line of intersection of the two faces i8 leading with reference to the direction of rotathereof is the leading edge with reference to the tion of the roll, and with the two faces of the direction of rotation of the roll and with the flanges l5 and I6 making equal angles with a faces of the peg making substantially equal anplane perpendicular to the axis of the roll. In 55 I the operation of driving the peg into the wooden plug, the wooden plug is split, in this instance into three parts 28, 29, and 30, as best shown in Fig. 2. The three parts exert wedging forces against said peg at approximately 120 degree angles. As a result, the peg I4 is securely held against movement in all directions. Preferably, the Wooden plug is made longer than the thickness of the wall of the husking roll, and when the peg is driven into the plug, the portion of the plug extending inwardly of the inner margin of the hole in the husking roll Wall, spreads outwardly as shown in Fig. 3. These outwardly spread portions of the wooden plug parts also aid in holding the peg in position and prevent the plug and peg from coming out.

What I claim is:

l. The combination with a husking roll having a radially extending hole in its periphery and adapted for rotation in one direction, of a wooden plug disposed in said hole, and a husking peg driven into said plug, said peg being angular in cross-section and positioned to dispose the edge at the line of intersection of the two faces thereof radially with respect to the axis of said roll with the faces making equal angles with a plane perpendicular to the axis of said roll and with said edge leading with reference to the direction of rotation of said roll. 4

2. The combination with a husking roll hav ing a radially extending hole in its periphery and adapted for rotation in one direction, of a wooden plug disposed in said hole, and a husking peg driven into said plug, said peg being angular in cross-section and positioned to dispose the edge at the line of intersection of the two faces thereof radially with respect to the axis of said roll with the faces making equal angles with a plane perpendicular to the axis of said roll and with said edge leading with reference to the direction of rotation of said roll, said plug being split into three parts by the driving of said peg into said plug, said three parts exerting a wedging force against said peg to securely wedge said peg in position.

3. The combination with a husking roll having a radially extending hole in its periphery and adapted for rotation in one direction, of a wooden plug disposed in said hole, and a husking peg driven into said plug, said peg being angular in cross-section, said plug being split into three parts by the driving of said peg into said plug, said three parts exerting a wedging force against said peg to securely wedge said peg in position.

4. The combination with a husking roll having a radially extending hole in its periphery and adapted for rotation in one direction, of a wooden plug disposed in said hole, and a husking peg driven into said plug, said peg being angular in cross-section, said plug being split into three parts by the driving of said peg into said plug, said three parts exerting wedging forces against said peg at 120 degree angles to securely wedge said peg in position.

5. The combination with a husking roll comprising a hollow tube and having a hole extending radially through the wall thereof and adapted for rotation in one, direction, of a wooden plug disposed in said opening, the inner end projecting beyond the inner margin of said opening, and a husking peg driven into said plug, said peg being angular in cross-section and positioned to dispose the edge at the line of intersection of the two faces thereof axially with respect to said hole and the leading edge with reference to the direction of rotation of said roll and with the faces of said peg making equal angles with a plane perpendicular to the axis of said roll, said plug being split into three parts by the driving of said peg into said plug, the three parts exerting wedging forces against said peg at 120 degree angles and the inwardly projecting end portions being spread beyond the margin of the hole to seclu'ely wedge and lock said peg in position.

6. The combination with a husking roll having a radially extending hole in its periphery and adapted for rotation in one direction, of a wooden plug disposed in said hole, and a husking peg driven into said plug, said peg being angular in cross-section and positioned to dispose the edge at the line of intersection of the two faces thereof radially with respect to the axis of said roll with the faces making equalangles with a plane perpendicular to the axis of said roll and with said edge leading with reference to the direction of rotation of said roll, the outer end of said peg lying in a plane perpendicular to said edge to form a relatively sharp point at the outer end of said edge.

7. In combination with a cylindrical husking roll, a husking peg of V-shaped cross section, comprising a pair of flange in a line extending longitudinally of said peg, and means for securing said peg to said roll in a position with said line of intersection extending substantially radially with respect to said roll.

8. In combination with a rotatable husking roll, a husking peg of V-shaped cross section, comprising a pair of converging flanges, and means for securing said peg to said roll in a position in which said flanges converge in the direc tionof movement of said peg as the roll rotates.

9. In combination with a husking roll, a husking peg having a pair of flange portions providing a pair of surfaces intersecting in a line extending longitudinally of said peg, said peg terminating at one end in a plane intersecting said surfaces to provide a sharp point for engaging ears of corn during husking operation, the other end of said peg having a tapered shank portion adapted to be driven into a plug supported in said roll.
